Guys - I have a 2015 John Deere 318D 1600hrs. After about 5 minutes of use I get an "Engine Derate 99%" error on my screen it quickly falls another 20-30% before I get it back to the shop. The Error codes it troughs "Fuel Pressure Sensor" and ECU 94.18 and ECU 94.18. So far I have: 1.) Replaced both fuel filters (And changed the oil / new air filters (unrelated I think) ) 2.) Replaced the fuel pressure sensor 3.) Replaced the fuel pump still getting the error. I'm thinking of dropping the fuel tank and checking for garbage in the tank. I don't think its Fuel quality issue as I have used BIO-Cide and this problem existed before it got cold enough to gel. Does anyone have any experience with this sort of problem, helpful hints or alternatives to try ? Thanks for any help and Merry Christmas ! - Stucake 2015 John Deere 318D
